GRIPPER FOR JOB PBESSES.
Specification of Letters Patent.
Patented Jan. 3, 1922.
Application filed. April 29, 1920. Serial No. 377,554.
To all whom it may concern Be it known that I, BARNEY B. RICE, a citizen of the United States, residing in the city of Redlands and State of California, have invented new and useful Improvements in Grippers for Job Presses, of which the following is a specification, reference being had to the accompanying drawings.
The present invention pertains to grippers for job presses, and the prime object is to provide an improved gripper which embodies cross bar at the outer end of the gripper, designed to facilitate the work of the gripper and to prevent the buckling of the paper in the process of printing.
It is well known amongst printers that as ordinarily constructed the free ends of the gripper permit the paper to buckle or stick to the type while being run through thepress. The present invention will obviate this difiiculty.
A practical embodiment of the invention is illustrated in the accompanying drawings, wherein:
Figure 1 is aplain view.
Figure 2, a side elevation.
Figure 3, a detail showing the method of locking the cross bar to the ends of the gripper.
The invention consists in cutting a series of transversely aligned, vertical slots as 1, 2, and 3, longitudinally along each of the gripper arms 4, said gripper arms being of the ordinary kind as now used. An auxiliary cross bar 5 is provided which is recessed at its ends, as shown at 6, to receive the outer ends of the gripper arms 4:, and so that said outer ends will set snugly up within the recesses 6 while the lower edge 7 of the cross bar will fall near the lower sides of the gripper arms 4. The cross bar 5 is then adjustably secured in place by means of suitable screwsS. v
The cross bar 5 may, of course, be locked in place between any two of the oppositely disposed slots 1, 2, and 3, so as to adjust the cross bar in the direction of its movement to spaced gripper arms provided at intervalsin their outer faces with transversely aligned recesses and having relatively short longitudinal slots located in the said recesses, an adjustable cross bar connecting the said arms and having its terminals arranged in two of the said recesses, and fastening devices piercing the cross bar and passing through the adjacent slots of the gripper arms and adapted to secure the cross bar in any of the transversely aligned recesses.
